Abstract: In various examples, a fan comprises a fan rotor, logic, and a component electrically coupled to the fan rotor to control operation of the fan rotor. The logic may determine that the component has failed. Responsive to determining that the component has failed, the logic to cause a backup component to apply power to the fan rotor, wherein applying the power causes blades of the fan to reduce spinning.
